Leak Testing

Print


WARNING
Before beginning this procedure, refer to the precautions at the beginning of this section. Use ONLY service equipment that is U.L. listed and certified to meet SAE J2210 requirements for removing HFC-134a (R-134A) from the A/C system.


CAUTION
A/C refrigerant or lubricant is an irritant and can irritate your eyes, nose and/or throat. Be very careful when connecting any service equipment. Do NOT breathe in any refrigerant or vapor. If accidental discharge occurs, thoroughly ventilate the work area before resuming service.

When an A/C System has been opened to the atmosphere, such as during installation or repair, it must be evacuated using a R-134a refrigerant Recovery/Recycling/Charging System. (If the system has been open for several days, the receiver/dryer should be replaced, and the system should be evacuated for several hours).


CAUTION
Compressed air mixed with R-134a forms a combustible vapor. The vapor can burn or explode causing grave injury. NEVER use compressed air to pressure test R-134a service equipment or vehicle A/C systems.

  1. Connect an R-134a refrigerant Recovery/Recycling/Charging System to the high-pressure service port and the low-pressure service port as shown. Make sure to follow the equipment manufacturer's instructions.

  2.  
  3. Open the high-pressure valve to charge the system to the specified capacity, then close the supply valve, and remove the charging system couplers. The refrigerant capacity is 36.1-37.9 oz (1025-1075 g).
  4.  
  5. Check the system for leaks using a suitable R-134a refrigerant leak detector with an accuracy of 0.5 ox (14g) per year or better.
  6.  
  7. If you find leaks that require the system to be opened (to repair or replace hoses, fittings, etc.) recover the A/C as outlined in this section.
  8.  
  9. After checking and repairing leaks, the A/C system must be evacuated, as outlined in this section.
